Ever since Ebay recently changed its checkout process, simply popping up a paypal login screen before returning to ebay to complete the payment I am also experiencing this problem. I have a Euro credit card and often buy items listed in Dollars, GBP, etc.
Previously, when, during ebay checkout, payment was completed within Paypal, I was able to select the Euro based card and also tell Paypal to bill me in the original currency, allowing my card issuer to make the currency conversion. This was always my choice as Paypal's exchaneg rates are terrible compared to my card issuer. However, in the new ebay checkout process, after logging into Paypal using the popup screen, one is returned to ebay to complete the payment and there one can select to pay with any bank account or card that has been registered to your Paypal account but there is no option to force Paypal to bill in the seller's original currency. Therefore one is always forced to accept Paypal's FX rates.
I even tried once to pay using credit card instead of using Paypal and the payment seemd to be made in the seller'soriginal currency but Paypal are still in the process handling the credit card trasaction for ebay and my card was billed in Euros once again, Paypal having applied their own exchange rates behind the scenes. This is surely anti-competitive and it will discourage me from buying via ebay in the future, I will instead probabyl switch to other sights where I am not forced to accept uncompetitive exchange rates every time I make a purchase.
